PHP日历显示几个

Question

I am doing a week-by-week (24 hour calendar), this is going to be used to record what hours have been booked and on what days.

It's like a timetable with slots that you book. To ensure that booked and unbooked slots were different I put in PHP if statements to check the time against the database.

Problem being; I believe my if statements are only working for one row unlike a while statement that works over several. - so basically I want to be able to book more than one hour per day - and see more than one hour per day

(the database insert isn't a problem - displaying it on the calendar is)

I cannot do a while statement as I am unsure how I would structure my schedule/calendar with one.

Here is an my problem: http://postimage.org/image/gcb3x3fk3/ (if I booked 18:00 on Sep 9 - it wouldn't show)

$globalid is a global variable and is not held within the file/code below (but is included)

MY CODE

<div id="calendar">
<?
if(isset($_POST['add_week'])){
    $week = date('d-m-Y', strtotime($_POST['last_week']));
    $new_week =  strtotime ( '+1 week' , strtotime ( $week ) ) ;
    $new_week = date('d-m-Y', $new_week);


    $week_number = date("W", strtotime( $new_week));
    $year = date("Y", strtotime( $new_week));
}else if(isset($_POST['back_week'])){
    $week = date('d-m-Y', strtotime($_POST['last_week']));
    $new_week =  strtotime ( '-1 week' , strtotime ( $week ) ) ;
    $new_week = date('d-m-Y', $new_week);


    $week_number = date("W", strtotime( $new_week));
    $year = date("Y", strtotime( $new_week));
}else{

$week_number = date("W");
$year = date("Y");
}
/*if($week_number < 10){
   $week_number = "0".$week_number;
}*/
$week_start = date('d-m-Y', strtotime($year."W".$week_number,0));

Answer 1

So huge and useless code.. Why not to loop through and from 100 lines of code have only 10? I tried to reorganize your code. So finally i have this one:

<div id="calendar">
<?php
    $week = date('d-m-Y', strtotime($_POST['last_week']));

    if(isset($_POST['add_week']))
        $new_week =  strtotime ( '+1 week' , strtotime ( $week ) ) ;
    if(isset($_POST['back_week']))
        $new_week =  strtotime ( '-1 week' , strtotime ( $week ) ) ;

    $new_week = date('d-m-Y', $new_week);

    if(!isset($_POST['add_week']) && !isset($_POST['back_week']))
    {
        $week_number = date("W");
        $year = date("Y");
    }
    else
    {
        $week_number = date("W", strtotime( $new_week));
        $year = date("Y", strtotime( $new_week));
    }

    $week_start = date('d-m-Y', strtotime($year."W".$week_number,0));
?>

<table name="week" width="100%" cellspacing="0" cellpadding="0" height="13">
    <tr>
<?
for($day=1; $day<=7; $day++)
{
?>
<tr>
    <td class="day">
        <?=$daycal = date('d M', strtotime($year."W".$week_number.$day))."";?>
    </td>

    <td width="3"> </td>
    <td>
    <!-- Timetable -->
    <table width="100%" cellspacing="0" cellpadding="0" height="13">
        <tr>
            <td>
            <?
                // Do not edit Below
                $cal = mysql_query("SELECT * FROM `calendar` WHERE `day`='$daycal' && `userid`='$globalid'")or die(mysql_error());
                $calendar = mysql_fetch_array($cal);

                for($cnt=0; $cnt<=24; $cnt++)
                { 
                    $hour = ($cnt<10?'0':'').$cnt.':00';
            ?>
                <div class="hour" name="<?=$hour?>" id="<? echo $daycal; ?>">
                    <?= ($calendar['time']==$hour) ? 'Booked' : $hour;  ?>
                </div>
            <? 
                } 
            ?>
            </td>
        </tr>
    </table>
    <!-- End Timetable -->
    </td>
</tr>
<tr height="3">
    <td> </td>
</tr>
<?
}
?>
</tr>
<tr>
    <form name="move_weeks" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
        <input type="hidden" name="last_week" value="<? echo $week_start; ?>" />
        <td colspan="7">
            <input type="submit" name="back_week" value="back_week" />
            <input type="submit" name="add_week" value="add_week" />
